Most materials have theoretical strengths far greater than their real strength because of the problems of grain structure.

Finally, lower temperatures can be used, which improves the grain structure.

But by all appearances its grain structure is admirably tight and inconspicuous.

The resulting grain structure is circumferential, which gives better mechanical properties.

The dyes used are clear and transparent chemicals that allow the grain structure of the leather to be seen.

It also claims improvements in grain structure and sharpness.

The times required depend on the grain structure of the alloy.

When the steel is heated again, the tiny grain structures merge.

A coarse grain structure impregnated with oil, however, may be the most desirable for wear resistance.

This has a more uniform grain structure and is referred to as "draw quality" material which limits tearing.
